FRANCIS B. BOALT, OF BINGHAM TON, NEW YORK.

DEVICE FOR HANGING DOORS.

SIECIFICAI'ION forming part of Letters Patent No.322,037, dated July 14, 1885.

Application filed June 6, 1885.

T 0 Mi whom it may concern.-

Be it known that I, FRAnoIsB. BOALT, of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Hanging Doors; and I do hereby declare that the following is a full, clear, and exact description thercof,re.ference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

Figure I is a top plan View of my improved door-hangers. Fig. 2 is a vertical longitudinal section of-the same. Fig. 3 is a sectional detail of the adjusting device.

The invention relates to improvements in the hanging of sliding doors, its object being to devise means by which the same can be easily moved, will be prevented from binding in their casings, and can be readily adj usted to hang with their upper and lower edges horizontal. These results are obtained by the construction and novel arrangement of parts hereinafter described, and pointed outin the appended claims.

Referring to the drawings by letter, A designates the door-casing, so constructed as to have the vertical chambers B B on each side of the doorways O.

D is the space above the said-chambers and doorways, and separated from the same by the horizontal rails E E.

Secured to the inner sides of the casing, just above the top of the doorway, and partially supported by the tops of the vertical strips 6 e, which stand inward from the edges of the doorways on each side, with just suffrcient room between the opposite ones for the door to pass easily between them into the chambers B, are the horizontal rails E,having an equal width between them, as shown.

F is the door, alittle wider than the doorway O, so as to entirely cover the latter when opposite thereto,and hung in place by the following means:

G G are rollers arraugedin pairs corresponding to the edges of the door, and adapted to travel on the rails E. The rollers of each pair arejournaled on the ends of a transverse shaft, H, in the central enlarged portion of which is journaled the outer end of an inclined rod or bar, I, preferably circular in (No model.)

transverse section. The inner ends of the rods I are connected by a vertically-movable joint, 73, to the opposite ends of a long block, J, provided on its lower surface with alongitudinal dovetailed groove adapted to move on a strip, K, of corresponding shape,secured centrally and longitudinally to the upper edge of the door, as shown.

L is a longitudinal screw situated in one side of the block J with its head over the opening edge of the door, and l is a bearing for said screw, secured to the upper edge of. the door. Z is a bracket secured to the side of the block J and provided'with a threaded opening, in'which the screw L engages. By these means the block is made longitudinally adjustable on the door.

M M are blocks standing upward and inward from the upper edge of the door, and provided with the inclined slots m, through which the rods I move, the said slots being vertically elongated to provide for the different inclinations of the rods. The blocks M serve as guides for the rods I and keep the rollers in proper place on the rails E.

The opening edge of the door is provided on each side with proper handles, f.

According to the foregoing description, the handles might be placed on either edge, and a stop on the same edge to prevent the door from entering the chamber B on that side, so that by changing the handles and stop to the opposite edge the direction of opening the door could be reversed; but most usually a chamber, B, would not be formed on the side of the casing from which the door opens.

For wide doorways double doors may be used, arranged to meet against a stop on the center of the sill, both doors being constructed as above described. The weight of the door,acting on the bearings of the rods I in the shaft H, will cause the door to hang vertical should the rails E be of unequal height, and should the upper and lower edges of the door be inclined to the horizontal the action of the screw L, by bring ing one of the other pair of rollers nearer to the central vertical line of the door, will rectify the same.

By passing the door into the chamber B the head of the screw is easily accessible.

Having described my invention, I claim- I. In hanging doors, the combination of the casing having the chambers on the side of the doorway, and the horizontal rails above the same, the door adapted to slide into said chambers, and provided on its edge with the longitudinal dovetailed strip, the block provided with a longitudinal dovetailed groove fitting and movable on said strip the inclined rods connected to the ends of the block by vertically-movingjoints, and the rollers moving on the rails of the casing and having the outer ends of the inclined rods journaled in the shafts, substantially as specified.

2. In hanging doors, the combination of the door provided on its upper edge with a longitudinal dovetailed strip, the block provided with a dovetailed groove fitting on said strip, the inclined rods connected by a vertically moving joint to the ends of the block andhaving their outer ends journaled in the shafts, and rollers adapted to more in horizontal Ways on the casing, and the screw turning in bean ings secured to the door and engaging a threaded opening in a bracket secured to the block, and thereby making the latter longitudinally adjustable on the door, substantially as specified.

3. In hanging doors, the combination, with the casing and ways secured thereto, of the door, the block made longitudinally adjustable thereon by means substantially as described, the inclined rods having their inner ends connected to the block by vertically-moving joints, and theirouter ends journaled in the shafts of rollers traveling on the ways of the casing, and the guide-blocks for the inclined rods securedto the upper edge of the door, substantially as specified.

4,. In hanging doors, the combination, with the casing provided with the rails E, and door F, provided with the dovetailed strip K, of the block J, inclined rods I,r0llers G, turning on the shafts H, guide-blocks M, and screw L, turning in the bearing Z, secured to the door,and engaging in a threaded opening in the bracket Z, secured to the block J, substantially as specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
